WASHING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 313,407, dated March 3,1885.

Application filed January 31, 1884. (No model.) v

To all whom it may concern.-

Be it known that I, LEANDER K. DUTTON, a citizen of the United States,residing at Oskaloosa, in the county of Mahaska and State of Iowa, haveinvented certain new and useful Improvements in XVashingMachines; and Ido declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itIO appertains to make and use the same, reference being had to theaccompanying drawings, and to letters or figures of reference markedthereon, which form a part of this specification.

Figure l of the drawings is a vertical sec tional view of my device, andFig. 2 is a longitudinal sectional view of the same.

This invention has relation to washing-machines; and it consists in theconstruction and novel arrangement of the zinc bottom-plate,

2o stamped with alternate sector-shaped series of corrugations taperingtoward the center, and smooth sector-shaped intervals; and of thecorrugated zinc rubbers on the sides o'f the box or tub, having each adovetail recess to receive 2 5 the body of a brush located in the middleof the rubber, all as hereinafter set forth.

In the accompanying drawings, the letter A designates the box or tub,having the bottom,

B and side walls, 0. v

D is the top through which passes the vertical pinion-shaft.

E represents the zinc bottom-plate, which is designed to be cut usuallya little smaller than the bottom of the tub, a marginal inter- 5 val ofan inch or more being left, so that the. plate may be nailed or screwedto the bottom B withfacility, and so that it will be perfectly flat, andwithout wrinkles. The plate E is pressed or stamped to providesector-shaped 0 series F of corrugations G, which alternate withsectorshaped smooth intervals H, these corrugated places and smoothplaces being radially arranged about a smooth center, K. Thecorrugations G are radial and taper from 5 their outer ends toward thecenter, as shown. The plate is made in this form so that the clothes orarticles being washed will, as they are carried around in the water bythe pins of the stirrer, be alternately operated upon by the rubbers andrelaxed, the loosening or'relaxation being designed to allow the clothesto fall at intervals, so as tobring them into more intimate engagementwith the rubbing corrugations, and to change their position somewhat asthey pass from one series of corruga 5 5 tions to another.

L L indicate the side rubbers, usually three in number, arranged uponthree sides of the box or tub. Each rubber consists of a strip of zinc,having on each side corrugations m, eX- tending vertically, and betweenthese a cen-' tral longitudinal recess, n, of dovetail form, adapted toreceive and hold a brush, P, which projects beyond the plate. The bodyof this brush (indicated at r) is made in dovetail form, so that it canbe easily passed into the dovetail channel or recess a of the plate, andreadily withdrawn therefrom when necessary. A strip or stop-piece, s,nailed or screwed to the box, is sufficient to hold the brush down, andcan be readily taken off when it is desired to remove the brush. Theside edges, t, of the plate L are bent backward and engage verticalgains 1) in the tub-wall. These side flanges, t, and gains are usuallysu ficient to hold the plates, the central channel abutting against thewall.

N represents the vertical pinion-shaft, upon 7 the lower end of which isapplied the triplearmed stirrer-frame Z, which is made with a centraleye or hub, w, and is secured to the shaft by means of a nut, a, appliedto the threaded lowerend of the shaft. Each arm I) of the stirrer-frameis formed with a deep socket, a, at its end, opening downward andserving to receive the tang d of the pin V, which extends downward intothe tub, and is designed to engage the clothes and carry them aroundwhen the shaft is turned. Usually the upper end of each socket 0 isprovided with an aperture, e, through which a threaded extremity, g, ofthe tang (1 projects, and a nut, 71, is applied thereon to hold the pinsecurely in position.

The pins V may be made smooth and tapering, or in other common form; butit'is preferred to make them in flattened tapering form, and with alongitudinal opening or slot, z, extending from a short distance belowthe shoulder k to near the lower end, Z. These linkform pins aredesigned to be very durable and very effective in their operation. I

The frame Z and the pins are designed to be made of malleable iron andgalvanized.

the frame to the shaft.

When the pins are made of wood, the arm- I recess and adapted to besecured to a tub, and

sockets are made open at top, and the ends of the pins are securedtherein by wedging a small piece of wood in a cleft made in the top ofthe pin.

The hub of the metallic stirrer-frame is provided with an annular flangeextending downward from its under side, forming a recess deep enough toreceive the nut which secures This annular flange a serves as a guard toprevent the clothes in the tub from coming in contact with the nut insuch a manner as to be injured.

Having described this invention, what I claim, and desire to secure byLetters Patent, 1s-

1. The zinc bottom formed from a single plate having stamped thereinalternate sectorshaped series of corrugations tapering toward thecenter, and smooth sectorshaped intervals, substantially as specified.

2. The combination of the corrugated zinc side rubber having a centralvertical dovetail the brush having a dovetail body, substantially asspecified.

3. The combination, with a corrugated zinc side rubber having lateralmarginal flanges extending backward, and a central dovetail recess, ofthe detachable brush having abody of dovetail form, and the tub havingthe vertical gains, substantially as specified.

4. As an organized element of machines of the character set forth, thecorrugated zinc rubber having a central dovetail recess, with thevertical corrugations on opposite sides thereof, and their ends bentbaekwardly to be secured in the side walls of a tub, substantially asspecified.

In testimony WhereofI affix my signature in presence of two witnesses.
